Protect the tool from impacts and stresses by keeping it in its case. Protect the tool from damp and excessive heat. Keep the tool away from corrosive substances. CONNECTIONS To avoid all sorts of problems when starting the tool you are recommended to observe the following: PNEUMATIC The pneumatic line is connected by a quick-release coupling hose to be attached to the air connection, thread size 1/4, supplied with the tool. The air supply hose must be flexible and must meet the safety requirements of the tool. AIR SUPPLY The air supply line must be free from dirt and damp to prevent the early wear of the moving components of the tool. Therefore, it is recommended to use dry air: i.e. not greased. PRELIMINARY CHECKS Before putting the tool into service you need to make a few inspections and checks in order to prevent errors or accidents while starting it. Check if the tool has been damaged during transportation. Check if the compressed air hose is accurately connected to the air supply line. Check if the tool turns freely and if the motor runs freely. PennEngineering www.pemnet.com 23
OPERATORS The tool is designed to be used by one operator only. Tool operators must satisfy the requirements stated hereafter (or they must be informed and trained accordingly). They must be aware of the manual herein and of all information relevant to safety: They must have some general and technical education, to a sufficient level to be able to understand the manual and to interpret the drawings and the diagrams correctly. They must be acquainted with the safety rules, and with the industrial-safety and technical instructions. They must have an overall knowledge of the line and of the factory in which the tool is installed. They must know how to act in case of emergency, where to find the individual protection means and how to use them correctly. Together with the above-mentioned requirements, the service technicians must also have appropriate technical training. MOTOR SCREWING ROTATES NONSTOP When the rotating pin (6 Part Number 4151500) is broken and you replace it, the motor may rotate continuously, which means that the shaft (13 Part Number 3761300) is too long; in this case it will have to be shortened by a few tenths to obtain the closure of the ball (14 Part Number 3096900). MOTOR UNSCREWING DOES NOT ROTATE Unlike the situation above, the shaft is too short and it has to be replaced with a new one, fitting it on the rotating pin (you will have to shorten it) in order to obtain the closure of the ball (14 Part Number 3096900). 24 PennEngineering www.pemnet.com
TOOL PREPARATION AND SCREW REPLACEMENT Warning: Tool setting and screw replacement must be carried out with the tool disconnected from the air supply line. There must be a distance of.060 / 1.5mm between the casing and the nut for motor screwing. To replace screws: Unscrew the adapter 4 from the tool. Insert joint 1. Insert screw 2. Insert screw adapter 3. Screw on adaptor 4 making sure that the screw (or tie rod) moves freely, and is not stiff. Screw on head 5. PennEngineering www.pemnet.com 25
White Yellow Orange WARNING!!! Pressure (force) must always be regulated as per maximum thickenss When screwing and unscrewing, you will see three rings (white, yellow, and orange). OIL (FORCE) PRESSURE REGULATION SETTINGS M3 / #4-40 - M4 / #8-32 - M5 / #10-32 - M6 / 1/4-20 - White Yellow Yellow Orange NOTE: These settings are general guidelines to the operator. Inserts are not uniform as hardness and therefore some modifications may be necessary (+ or -). IMPORTANT: OIL PRESSURE ADJUSTMENT - When turing right, screwing force increases. When turning left, force decreases. WARNING: When the pressure adjustment screw is completely tightened, unscrewing must be done at a pressure of 100 PSI / 6.5 BAR or greater. 26 PennEngineering www.pemnet.com
INFORMATION EMERGENCY REVERSE BUTTON To be used to remove an unsuitable insert AIR DISTRIBUTOR PRESSURE (FORCE) REGULATOR WARNING: The unscrewing cycle may not occur when he rivet nut is not mounted on the screw (tie rod); the manostat isn t under pressure. When the oil is not under pressure, you can not unscrew. PennEngineering www.pemnet.com 27
(1) Insert is stuck. (2) Keep the trigger pressed and rotate to help loosen. (3) If this does not work. (4) Disconnect the air hose. (5) Insert the Emergency Regulation Pin in the proper holes, manually unscrewing the tool. 28 PennEngineering www.pemnet.com
MAINTENANCE Maintenance operations must be carried out with the tool stopped and disconnected from the pneumatic supply line. Warnings: The tool maintenance instructions must be followed carefully. To ensure safety and perfect tool efficiency, it is recommended to use exclusively ORIGINAL spare parts. CLEANING It is a good rule to completely clean and grease the tool on a periodic basis (depending on the type and frequency of use). These operations must be carried out at least once a year. Shut-off all sources of power to the tool. The operator must wear and use suitable personal protections before starting to clean the tool. ORDINARY MAINTENANCE In order to prevent stoppages and faults of the tool, an ordinary maintenance (including inspections, checks and operations) must be scheduled to keep the following under systematic control: State of lubrication of the tool. State of wear of consumable parts. REFILLING THE HYDRAULIC CIRCUIT WITH OIL The hydraulic circuit needs to be refilled with oil after a continuous use, and when you notice a reduction in the tool stroke. Proceed as follows (see photo at right): Disconnect the airline from the tool inlet. Unscrew the manostat (A) with a wrench. Remove cap together with relevant washer 27. Put the tool in horizontal position and slowly pour in the hydraulic oil (ISO VG 32 type) 50 until the circuit is full. Screw cap back on, together with relevant washer 27. Connect the tool to compressed air line and start up a couple of idle cycles. Stop pulling the trigger and slowly loosen screw 27; make sure that the circuit is full with oil and that no air bubbles are left inside. Wear gloves when managing the oil. Do not throw the old oil outdoors. Hand it over to an authorized waste disposal center. Warning!: If you should accidentally spill oil on your skin, wash and rinse thoroughly with soap and water. PARTS SUBJECT TO WEAR On a periodic basis check the rubber base for wear, as this is what ensures the stability of the tool. If it should need replacing, order the spare base from PennEngineering indicating the year/serial number of the tool. On a periodic basis check the screws and heads for wear and, if necessary, replace them as indicated (page 20). PennEngineering www.pemnet.com 29
FAULT DIAGNOSIS PROBLEM No traction SOLUTION Tool needs oil. After installing rivet nut, tool does not unscrew properly Not enough oil in tool. Check O-ring (B) and replace if necessary. When you have to work on the pressure switch: 1. Remove air 2. Loosen the oil cap (27) carefully keeping gasket (C) from coming out. If replacing, use guide (1). If after reassembling all parts of the pressure switch and tool does not work properly, O-rings (O1, O2, O3) have not been correctly assembled: O-ring (O2) when broken unscrews without making traction O-ring (O3) makes traction but no unscrew O-ring (O1) can leak air Consequently, it is advisable to replace all 3 O-rings (ORM 15x1) of the kit (ref. 41) part number 4157200. REF. PART NUMBER DESCRIPTION 1 4380800 Guide bushing to insert Ø 9 lip seal, located at the bottom of the seat of the pressure switch (ref. C) 2 4381200 Ø 9 lip seal (ref. C) 3 Ø 8 commercial punches Items 1 and 2 are special order (please refer to Rivit part numbers). 30 PennEngineering www.pemnet.com 2011 Rev. 911
PROBLEM SOLUTION Air leaks from muffler Check the two O-rings (O4) and O-ring (21 part number 3235600) which could be worn or broken Motor rotates continuously When the rotating pin (6 part number 4151500) is broken and you replace it, it may happen that the motor rotates continuously, which means that the shaft (13 part number 3761300) is too long; in this case, it will have to be shortened by a few tenths to obtain the closure of the ball (14 part number 3096900). Unlike the situation above, the shaft is too short and it has to be replaced with a new one, fitting it without end float, witht he air on, in order to obtain the closure of the ball (14 part number 3096900). Quick kit assembly When assembling the quick kit (part number 4176900), with air off, make sure to create an axial space of 1.5mm allowing the pin to move freely. Loss of revolutions during unscrewing When you overwork the tool, there may be a loss of revolutions during unscrewing; it is necessary to remove the air hose and add a few drops of oil in the air hose connection and push button (P) for a couple of minutes.
